SPECIFICATION forming part of Letters Patent No. 309,082, dated December 9, 1884:.

Application filed A mil 9, 189-!.

To all 11/71/0712 it 'IIMl-Zj concern.-

Be it known that I, JAMES I\[UN170N, a subject of the Queen of Great Britain, residing in Maywood, in the county of Cook and State of Illinois, have invented a new and useful I1nprovenientin Tire-Halling-Kaehines, of which the following is a specification.

This invention relates to machines for rolling tires, and its object isto prevent iinsbeing formed upon the tire as it is rolled.

I-Ierctoibre I have made tire-rel l i ng machines which were provided with cutters or devices lorremoving these fins from the bottom and top edges ol'the ti re while the tire was being rolled and as fast as they formed thereon; but I have discovered in the present invention that by slightly bcveling the collars oi the rolls and employing a pair of horizontal rolls to press against the edges of the tire no fin what-ever will beibrmed upon either edge of the tire, as, owing to the bevel form of their collars, the main rolls will merely form at each revolution or passage of the tire between them slight ridges or projections on the edges of the tire, which ridges or projections are instantly pressed back by the horizontal rolls, and the edges of the tire rendered straight and smooth before again passing between the main rolls. In this way, no fins whatever bcin g formed upon the tire, there is of course neither any waste of metal nor any labor required in their removal.

In the accompanying drawings, which form a part of this specification, Figure 1 is a plan View oi'a device embodyingmyinvention. Fig. 2 isaside elevation ol' thehorizontial rolls. Fig. 3 is avcrtical section on line 3 3 of Fig. 1; and Fig. 4 is an enlarged ci'ossscction oi the tire, showing the form of the same alter leaving the main rolls and before reaching the horizontal or smoothing rolls, the ridges or projections upon the edges or the tire being somewhat exaggerated for the purpose of better illustrating the same.

In said drawings, A represents the frame or bed of a tire-rolling machine, or of that portion of it to which my invention appertains.

B is the outer or fixedroll; B, the inner or movable roll; (I, the tire, and Gthe horizontal supporting-rollers upon which the tire rests and revolves. The rolls I3 and B are box- (No mode-l.)

rollsthat is to say, are both provided with collars or flanges Z) I) and b b, so that there can be no tendency of any fins to form at the corners of the tire. n lars or flanges 6 Z) have bevel-surlaccs I) b", which bevel-surfaces may extend back the full depth of the collars; or the inner part of the collar may be straight,whilc the outer portion only is beveled. As the tire U passes between the rolls having these bevel collars or 'llanges slight ridges 0 will be formed upon its edges usually two ridges or projections with a de pression, 0, between them.

I) and I) are the upper and lower horizontal rolls, which press against the edges of the tire and serve to force or press these little ridges c back,and to render the edges of the tire straight and smooth. The lower rolls, I), are stationary, and are journaled in suitable bearings upon the frame of the machine, and serve also to support the tire the same as the rollers t). The upper rolls, I), are mounted on the wings or pivoted segments II, so that they may be swung to and from the tire by means of the usual hand-wheel, 7;,and worm /1.,whicn en gages with the teeth if of the segments. The rolls 1) are also :uljustable vertically by means of the screws (1, the bearings or boxes of said rolls being arranged to slide vertieallyin their housings II, in the ordinary manner. Ily means of the screws d, which are provided with suitable hand-levers, 1, the rolls I.) l.) and I) I) may be set so as to exert any desired degree of pressure upon the tire, or such as is necessary to keep its edges straight and smooth. it will of course be iniderstood by those skilled in the art that heretofore in tire-rollingmachines one or more upper rolls, 1) I), have been use to keep the tire down upon its supporting-rolls DI) U. I and E are the vertical guide-rollers, mounted on the segments II in the nsnalway.

The degree of pressure required upon the horizontal rolls D and D in order to obliterate the ridges c and keep the edges of the tire straight and smooth is ordinarily not so great as to makeit necessary to drive them; but one or more of the under rolls, 1), may be driven, if preferred. In this way the tire is given a much smoother and iiner finish upon its edges than can be produced in the old way, where removed either fins are formed and have to be The inner edges of these colduring the process of rolling or after it is completed.

I am aware that heretofore horizontal rolls to bear upon the edges of the tire have been known or employed in connection with the usual main or vertical rolls, having either no collars or flanges at all, or else square collars or flanges, and I therefore disclaim the same as forming no part of my invention.

In my invention the main or vertical rolls have bevel collars or flanges, which perform the function of preventing the formation of a thin film or iin upon the edge of the tire, and of producing in place of such fin simply low swells, ridges, or enlargements on the surface of the edge ofthe tire, so that when rolls having such bevel collars are combined with horizontal rolls pressing upon the edges of 1 the tire said horizontal rolls will serve the function of pressing out such low swells or'ridges, and thus rendering the edges of the tire again perfectly flat and smooth each time it passes between the main rolls.

It is obvious that if the construction of the main rolls is such as to produce upon the edges at l or corners of the tire a thin fin the operation of the horizontal rolls would tend simply to flatten it down upon the surface or edge of the tire, and not to force the metal of the fin back into the body of the tire, as is the case where low ridges or swells are produced upon the edges of the tire; and with such construction of the main rolls, therefore, my invention is not present either in form or mode of operation, nor is the new and useful result effected by it accomplished.

I claim- 1. In atire-rolling machine, the combination of the rolls B B,having bevel collars or flanges, with horizontal rolls D D, to straighten and smooth the edges of the tire and prevent the formation offins thereon as it is rolled, substantially as specified.

2. The rolls B B, provided with collars or flanges b b and b I), having bevel-surfiices I) b, substantially as specified.
